Pin retaining clips for Kelsey Model U 5 x 8
Two questions - any help appreciated
Question 1:
I just picked up a Kelsey Model U 5 x 8. I had to take it apart to take it on a flight (I was on vacation and found it at a garage sale) and I was hoping to get some new pin retaining clips prior to reassembling it.
The parts I am looking for are the little spring washer things that go on the ends of the metal pins that hold the press together. I attached a crude picture. They look like a washer with teeth on the inside. Some of them got a little bent during removal and I’m not sure if they will look good if I re-use them.
I found some that are similar and should work but they have a different number of teeth on the inside - I think the originals have 9 but I would have to double check. I would like to preserve the original look if possible.
If anyone knows…
1) The proper name for this part
2) A specific place where you can get them online
please let me know!
Question 2:
Is there a tool for driving the pins back into place - maybe like a pin vise or arbor press? In a pinch I used a hammer and wooden dowel rod to remove them but I would prefer to use safer method to replace them to minimize the risk of shattering the castings.
If there is a specialized tool, aside from simply using a vise, does anyone know what the proper name is?
Thanks in advance!

These will work though not exactly like the originals.

Your press has .500” shafts. In latter years Kelsey used the external snap ring.

Though your shafts do not have grooves these will work fine to prevent lateral shaft creep. You will need a pair of snap ring pliers to install. like these

Installing the internal toothed retaining ring correctly will require a unique die that is deep enough to tap the ring on squarely. Perhaps magnetized to hold the ring. I have never seen a commercialy available installation tool for this type of ring.

Tom did a very good job explaining what you need in order to hold the pins in place. We switched to the “C” shaped retaining clips around 1975, as the toothed rings were difficult to use. We did have a special tool to hold them in place but it was not as easy to use as the snap ring pliers.
All we ever used was a hammer to drive the pins. Not sure of the vintage of your unit, but the pins used in the 60’s and 70’s had a chamfer on either end of the pin to aid the insertion. Sometimes we used a tapered rod inserted from the opposite end of the holes to help line things up. A little lubrication would not hurt. Normally the castings were pretty strong so they could withstand some blunt force.
